Locks, of which the tion.

This invention relates to locks for doors of railroad freight cars andit has for its object to produce a simple and efficient locking devicewhich may be installed at a moderate expense.

A further object of the invention is to provide a simple and improvedlocking device whereby the door may be securely locked while partly opento permit ventilation of following is a specificathe contents of the carwithout admitting depredators.

A still further object of the invention is to construct a simple andefficient locking device which instead of weakening will serve to braceand to reinforce the doors to which it. is applied.

A still further object of the invention is to provide a simple andefiicient locking device which will not be injuriously affected or itsoperation interfered with by snow and Still further objects of tosimplify and improve the general construction and operation of a deviceof the character referred to.

lVith these andother ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being however understood that no limitation isnecessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvent-ion, may be resorted to when desired.

In the drawings: Figure 1 is a view showing in elevation portions of acar frame and door equipped with the improved locking device. Fig. 2 isa perspective view showing the invention are i The staple member of theimproved device which is shown at A comprises an elongated bar providedupon its under surface with sharp edged lugs or projections 5-5 ofapproximately triangular cross section adjacent to which apertures 6 areformed for the passage of bolts or other fastening members. The plate orbar A is provided adjacent-to one end with a hook-shaped extension 7 thenose of which 8 projects below the level of the under surface of thebar. It will be evident that when the said bar is mounted 1 in positionupon a car door and is drawn j tight by the bolts or other fasteningmeans, the lugs or projections 5 will enter into the i wood and add tothe simplicity of the fastening while the nose of the hook will likewisej enter into the wood of the car door where a small recess or socket maypreviously be formed for its reception; the said hook, or the projectingportion thereof, will thus form an eye or staple that serves to hold thej door hasp very securely in position.

The door hasp B consists of an elongated plate or bar having adjacent toone end an eye 9 engaging the hook 7 the bar B is formed with anintermediate offset portion j 10 whereby the outer end of said bar isofiset in an outward direction so that the outer end of said bar willlie in a proper plane to engage the latch mechanism to be presentlydescribed. Said door hasp is provided upon j its underside, intermediatethe ends thereof with a transversely disposed stop member 11 having avertical side wall 12 facing the supported end of the door hasp; thelatter is provided at and near its free end with additional stop members13 having side walls 14 i facing in the direction of each other and at lapproximately right angles to the body of the door hasp.

The latch mechanism proper, shown at C comprises a base plate 15 havingupon the boss orprojection 16, the side upwardly inclined or Adjacent tothe upper face thereof, a walls of which have i beveled portions 17 endof the boss 16 are formed lugs or projections 18 between which a lockhasp 19 is pivotally supported; a catch member D is formed adjacent tothe lower end of the boss, said catch member being provided with a doorhasp receiving recess 20, the bottom of which is beveled or tapered asshown at 21 from an intermediate point downwardly to its side edges. Thefree end of the lock hasp 19 is bifurcated as shown at 22 to straddle aterminal eye or keeper 23 formed upon the catch member D, and the saidlock hasp is provided on its under side with a concaved recess 24 andwith a sharp edged projection 25, the latter constituting a stop whichby engagement with the base plate or with the boss or projection uponthe latter serves to limit the movement of the lock hasp in thedirection of the base plate. The stop 25 also serves to engage the upperedge of the door hasp when the latter is placed in engagement with thecatch member. The eye or keeper may be utilized for the reception of afastening member such as a pad lock which when placed in position willsecure the lock hasp in engagement with the catch member; said lock haspand catch member being also shown as provided with registering apertures26 through which the wire 27 of an ordinary car seal may be passed whendesired. The base member 15 of the latch device is provided adjacent toits ends with apertures 28 for the passage of fastening members such asbolts or the like whereby the latch device may be secured upon the cardoor frame or upon the car body in suitable position for operation.

From the foregoing description taken in connection with the drawingshereto annexed, the operation of this invention and its advantages willbe readily understood by those skilled in the art to which itappertains. It will be readily seen that when the parts are mounted inproper relative position, the car door when closed, may be secured byplacing the door hasp in engagement with the catch of the latchingdevice in such a manner that the stop member 12 will abut upon the edgeof the base plate or boss of the latching device distant from the dooropening, after which the lock hasp may be placed in engagement with thecatch and secured in any manner that may be preferred. It will beobserved that when the door hasp is manipulated to place it in catchengaging position, the stop member 11 will first engage the beveledportion of one of the side walls of the boss 16 after which, by forcingthe said door hasp home, sufficient leverage will be exerted to eifect aver tight closure of the door after which the part will be held againstrattling and the strain and danger of displacement and breakage causedthereby. Another important and valuable feature resides in the beveledconformation of the bottom of the door hasp receiving recess owing towhich, if said recess should have become blocked by ice, or snow, .aquick downward movement of the door hasp inevitably results indisplacing said snow and ice instead of compressing it and leaving it toform an annoying obstruction. Furthermore, when the lock hasp is movedto an engaging position, any ice which may have become incrusted uponthe face of the base bar will be broken by the sharp edge of the stopmember 25 and will be displaced upwardly under the concavity or recessin the underside of the lock hasp from which it will readily escape toeither side.

Should it be desired to leave the car door slightly open forventilation, this may be accomplished by placing the stop members 3 inengagement with the sides of the boss 16 when the car door willobviously be secured in a slightly open position, the extent of the slotor opening being equal to the dis tance between the engaging side wallsof the outermost stop member 13 and that of the stop member 11.

his improved locking device for car doors is not only simple inconstruction and easily operated, but it may be installed upon freightcars of present construction at a very moderate expense, and many of theobjections and disadvantages of car door fastenings now in use areentirely overcome by this device. Shaking and rattling will be partiallyif not entirely prevented, and the damages due to this source will beavoided.
